Generally, the service life of excavators is 10-15 years, but basically after 5000 hours of use, various problems will begin to appear. Therefore, maintenance should be done not only within 5000 hours, but also after 5000 hours. So what methods can prolong the service life of the excavator? The methods to prolong the service life are described below for reference only.
1. Correctly use the excavator and strictly implement the safety technical operation procedures. Implement target cost management for mechanical equipment to link the economic benefits of the operator with the use fees of the excavator, such as fuel cost, maintenance cost, material cost, tool cost, etc. Set the excavator driver's passive daily maintenance equipment as active daily maintenance.
2. Reduce the wear of excavator caused by environmental climate, that is, reduce the impact of environmental factors on its service life. Since most of the construction machinery is operated in the open air and the operation site changes frequently, its performance is greatly affected by the temperature, environment, climate and other factors of the operation site. The machinery for long-term fixed operation must have a parking room or shed, or take the maintenance measures of covering the upper part and supporting the lower part with wood, so as to reduce the wear caused by sunlight, rain and corrosion. Due to the neglect of the impact of environmental factors on the use of excavators, such as the low ambient temperature will cause serious wear to the machinery, and the failure to take corresponding protective or adaptive measures, the use performance of excavators is reduced, the service life is shortened, and even accidents are caused.
3. Regular maintenance of excavator is the key to prolong its service life. However, when the construction period is tight and the task is heavy, many construction units often ignore the maintenance work and think that there is no need for maintenance if there is no fault in the normal operation of machinery, which is easy to cause mechanical accidents. Because maintenance can eliminate mechanical hidden dangers. If it is not maintained in time, it will often cause serious faults of mechanical equipment and even casualties. This not only increases the maintenance cost, but also delays the construction period.
4. Adopt advanced mechanical inspection and other auxiliary maintenance means. Mechanical maintenance is an important part of prolonging the service life of machinery. Adopting reasonable maintenance methods can effectively prolong the service life of construction machinery. According to the statistics of relevant data, the use of advanced condition monitoring means can reduce the maintenance cost by 25% ~ 50%, reduce the failure rate by 75%, and prolong the service life of the machinery.
